Description of intervention(s) / exposure
Treatment: Drugs - Telotristat etiprate
Treatment: Drugs - Placebo

Experimental: 250 mg Telotristat Etiprate - Following a 3 to 4-week run-in period, participants were randomized to receive one 250 mg telotristat etiprate tablet and one placebo-matching telotristat etiprate tablet administered three times daily for 12 weeks, followed by a 36 week open-label extension period.

Experimental: 500 mg Telotristat Etiprate - Following a 3 to 4-week run-in period, participants were randomized to receive one 250 mg telotristat etiprate tablet and one placebo-matching telotristat etiprate tablet administered three times daily for one week, followed by two 250 mg telotristat etiprate tablets administered three times daily for 11 weeks in the 12 week double-blind treatment period, followed by a 36 week open-label extension period.

Placebo comparator: Placebo - Following a 3 to 4-week run-in period, participants were randomized to receive two placebo-matching telotristat etiprate tablets administered three times daily for 12 weeks, followed by a 36 week open-label extension period.
